TheNCE-T (Network Cloud Engine - Transport)fully supportsvirtualization deployment. It can be deployed as a virtualized application on cloud platforms, leveraging technologies like VMware, OpenStack, or Kubernetes.

Key benefits of virtualization:

Scalability:Virtualized deployment allows NCE-T to scale dynamically based on network demands.

Flexibility:Enables integration with cloud-native environments and multi-vendor ecosystems.

Cost Efficiency:Reduces hardware dependency by running on shared infrastructure.

The statement that NCE-T does not support virtualization is therefore incorrect.

Huawei Cloud-Native Networking Best Practices

The correct answer isRoom-like scenarios, including education, hotel, medical, apartment. Campus OptiX (POL) is primarily designed for enterprise campus environments where high bandwidth, low latency, and simplified network architecture are required. Common scenarios include:

Education:Connecting classrooms, dormitories, and administrative offices.

Hotels:Providing high-speed internet and IPTV services to guests.

Medical:Supporting hospital networks for patient care, imaging, and telemedicine.

Apartments:Delivering triple-play services (data, voice, video) to residents.

While options like video backhaul and Wi-Fi backhaul are valid use cases for optical networks, they are typically associated with carrier-grade solutions rather than enterprise-focused Campus OptiX deployments.

TheOptiXtrans product familyprimarily includes advanced optical transport platforms such as theE9600 series, which is designed for high-capacity and long-haul networks. However, theOSN 1800,DC908, andE5800are part of different product lines:

OSN 1800:Belongs to Huawei's MS-OTN (Multi-Service Optical Transport Network) portfolio, targeting metro and regional networks.

DC908:A data center interconnect (DCI) solution optimized for short-reach, high-capacity links between data centers.

E5800:Not a recognized product in Huawei's optical transport portfolio.

Thus, the statement is incorrect because not all the listed products belong to the OptiXtrans family.

The statement isTrue. Huawei holds theNo.1 market sharein theMetro & Access WDM (Wavelength Division Multiplexing)segment, according to industry reports from organizations like Dell’Oro Group and Omdia.

Here’s why Huawei leads the market:

Innovative Technology:Huawei has consistently invested in cutting-edge technologies like OTN, MS-OTN, and advanced modulation schemes (e.g., QPSK, QAM) to deliver high-capacity, low-latency solutions.

Comprehensive Portfolio:Huawei offers a wide range of WDM products, including the OSN series (e.g., OSN 9800, OSN 1800), OptiXtrans series, and DCI solutions, catering to diverse customer needs.

Global Reach:Huawei’s solutions are deployed worldwide, serving industries such as telecommunications, utilities, transportation, and enterprises.

Customer-Centric Approach:Huawei provides tailored solutions for specific use cases, such as smart grids, safe cities, and data center interconnects, enhancing its market leadership.

This leadership reflects Huawei’s commitment to innovation, quality, and customer satisfaction in the optical networking space.

TheFTTH (Fiber-to-the-Home)network consists of several key components that work together todeliver high-speed connectivity to end-users:

ONU/ONT (Optical Network Unit/Terminal):Customer-side device that converts optical signals into electrical signals for end-user devices.

OLT (Optical Line Terminal):Central device located at the service provider's premises, managing communication with multiple ONUs.

Splitter:Passive optical device that divides the signal from the OLT into multiple paths for distribution to ONUs.

NMS (Network Management System):Software platform (e.g., eSight) for centralized monitoring and management of the FTTH network.

ODF (Optical Distribution Frame):Infrastructure component used for organizing and connecting optical fibers.

Each of these components plays a critical role in ensuring efficient and reliable FTTH deployments.

The statement isFalse. TheNCE-T (Network Cloud Engine for Transport) does support virtualization deployment, making it highly flexible and scalable for modern optical transportnetworks.

Key aspects of NCE-T’s virtualization support include:

Cloud-Native Design:NCE-T can be deployed on cloud platforms, leveraging virtual machines (VMs) or containers for scalability and resource optimization.

Multi-Tenancy:Supports multiple tenants within a single instance, enabling service providers to offer customized solutions to different customers.

Dynamic Scaling:Automatically adjusts resource allocation based on network demand, ensuring optimal performance during peak loads.

Integration with NFV:Works seamlessly with Network Function Virtualization (NFV) frameworks, enabling convergence with other virtualized network functions.

Virtualization enhances NCE-T’s capabilities, making it suitable for large-scale, carrier-grade deployments where flexibility and scalability are critical.

The correct answer isThe management capacity is less than 1000 equivalent NEs. TheNCE-T Liteis a lightweight version of Huawei’sNCE-Tplatform, designed for small to medium-sized optical transport networks with limited management needs.

Key characteristics of NCE-T Lite include:

Scalability:Supports up to1000 equivalent NEs (Network Elements), making it suitable for smaller networks like enterprise campuses, regional ISPs, or edge locations.

Cost Efficiency:Offers a simplified feature set compared to the full NCE-T, reducing costs for organizations with limited budgets.

Ease of Deployment:Simplifies network operations with centralized monitoring, configuration, and troubleshooting capabilities.

Use Cases:Ideal for scenarios where high-end features like advanced analytics or large-scale orchestration are not required.

Other options:

More than 5000, 4000, or 3000 NEs:These refer to larger-scale deployments that exceed the capacity of NCE-T Lite. For such scenarios, the full version of NCE-T or other advanced management platforms would be required.

NCE-T Lite strikes a balance between functionality and affordability, making it accessible for organizations with modest network requirements.

The correct answer isMD02A. TheMD02A boardin theOptiXtrans DC908platform supports400G per wavelength, enabling high-capacity data transmission for backbone and core networks.

Key features of the MD02A board include:

High-Speed Transmission:Supports data rates up to400G per wavelength, leveraging advanced modulation techniques like DP-16QAM.

Flexibility:Compatible with various network architectures, including OTN, WDM, and Ethernet.

Scalability:Can be integrated into existing networks to boost capacity without requiring a complete overhaul.

Efficiency:Optimizes spectral efficiency, maximizing the utilization of available fiber resources.

Other options:

MD02:An earlier version of the board, typically supporting lower data rates.

MS04:Focuses on mid-range applications, not 400G.

N602:Designed for access networks rather than high-speed backbone transmission.

TheNCE-T Liteis a simplified version of theNCE-T (Network Cloud Engine - Transport), designed for smaller-scale deployments or scenarios with limited resource requirements. Unlike the full version of NCE-T,NCE-T Lite does NOT support virtualization deployment.

Key details:

Deployment Model:NCE-T Lite is typically deployed as a standalone application on bare-metal servers rather than in virtualized environments.

Resource Constraints:It is optimized for environments where virtualization infrastructure (e.g., VMware, OpenStack) may not be available or practical.

Functionality:While it provides essential network management and control capabilities, it lacks the scalability and flexibility of the full NCE-T platform.

Thus, the statement is correct.
